Composition for circuit board manufacture

A process and composition for treating a metal surface to increase its surface roughness for subsequent adhesion to a polymer layer. The composition comprises hydrogen peroxide, inorganic acid, an amine free of a surfactant group and optionally, a corrosion inhibitor. The composition is characterize...

Beschreibung
Zusammenfassung:	A process and composition for treating a metal surface to increase its surface roughness for subsequent adhesion to a polymer layer. The composition comprises hydrogen peroxide, inorganic acid, an amine free of a surfactant group and optionally, a corrosion inhibitor. The composition is characterized by elimination of a surfactant from solution.
